JAMES E. MCNAUGHTON, OF MANCHESTER, VER-MONT.,

CHARCOAL-KILN.

SPECIFICATION forming part of Letters Patent No. 360,238, dated March 29, 1887.

Application tiled September 2, 1886. Serial No. ll-2,515. (No model.)

To @ZZ whom t may concern:

Be it known that I, JAMES E. McNkUeriroN, a citizen of the United States, residing at Manchester,in the county of Bennington and State of Vermont, have invented certain new and useful Improvements in Charcoal-Kilns, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to certain new and useful improvements in the construction of metallic kilns or ovens for burning charcoal.

The invention has for its object to provide a kiln of simple and practical construction that may readily be taken apart for transportation from place to place when desired, and that will he especially adapted for convenience and rapidity of charging and emptying,as will be more fully hereinafter described.

The apparatus consists in certain novel features of construction, that will be set forth hereinafter, and particularly pointed out in the claim appended.

In the accompanying drawings,Figure I represents a perspective view of the improved kiln or oven; Fig. 2, a transverse sectional view, and Fig. 3 a side view of one end.

In these drawings, A designates a series of uprights planted or secured in the ground on each side of the kiln proper, and connected by a series of crossbars, B, extending across the top of the kiln, as shown, for the purpose of supporting and bracing the kiln. Between the said uprights A are arranged the sides C of the kiln, each of which consist, preferably, of two long sheets of thin boiler-iron united by rivets, as shown. The lower sections of the sides are provided with two or more rows of apertures of the proper size and distance apart for the proper supply of air to the burning Wood. These sides are secured to the uprights or posts A by means of'angle irons D, to be hereinafter again referred to. The slightly-arched roof E is also preferably composed of two sheets of thin boiler-iron, flanged at their edges and properly riveted together down the center of the furnace, forming a flange extending from end to end, as shown. An opening, F, may be made in the said roof, for the purpose'of firing the kiln and for the escape of the gas. The longitudinal edges of the roof are provided with down-` wardly-extending anges G,which are adapted to set over the upper edges ofthe sides C and be partially supported thereby.

The portions of the angle-irons D that are riveted to the sides of the kiln have their upper and inner edges beveled, so as to form recesses for the reception of the flanges G of the roof for the purpose of materially aiding in the support of the same. To further support the root' I use eyebolts II,which pass through the crossheams B, and are attached to the central flange formed down the center of the roof by the union of the two sections thereof. The ends I, of the kiln also consist of thin sheets of boiler-iron, and may be provided with airsupply openings similar' to those in the sides of the apparatus.

On the ends of the side and roof sections, and projecting beyond both ends of the kiln, are secured a series of pins or studs, J ,which are adapted to iit in coincident openings in the end plates Ito detachably secure the saine in place, as will be obvious.

Suitable doors, L, may be in one or both of the end plates, as may be desired.

l/Vhen it is desired to charge the kiln, one or both of the end plates may be removed by simply sliding them offthe pins on the side and roof sections, and when the apparatus has been illed the end plates may as easily be replaced, and the apparatus will be ready for operation.

The principal advantage of this invention is that all the parts are constructed of such comparatively light material and in such a manner as to allow them to be readily detached for transportation from place to place whenever it becomes necessary, which fact is of great importance in this class of apparatus, as those acquainted with the art to which it appertains will observe. Another great advantage is that by making the ends removable the kiln may be quickly and conveniently filled, and as readily emptied.

It is obvious that,in case I desire to enlarge the kiln,I may construct the roof and side sections of a number of sheets of iron, as the eXigencies of the case may require,without in the least departing from the spirit of my invention.

Being aware that it is not new 'to construct portable charcoalkilns of metallic. plates bolted together, and to provide such kilns with air-supply openings at or near the ground, I wish it understood that I do not claim such construction as my invention.

I am aware that it is old in kilns to construct the same of sheet-metal plates riveted together and braced in a practical position. Such kilns have been made in the form of parallelograms, domes, and in other forms. They have been sustained by independent frames and eye-suspending bolts. Such devices I disclaim. Y

I am not aware that a rectangular knockdown kiln constructed as described by me has ever been provided with removable ends applied,as described,by sustaining-pins,and provided with doors, whereby the said ends can be readily detached and Wagons backed into the kilns to conveniently remove the charcoal.
